## About The Pull Request

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->
Adds a huge ass crowbar to robotics (the mech removal tool), it deals 5
damage unwielded, or 19 wielded. (should be fine, considering robotics
also has the easiest access to the materials needed for a chainsaw)
You can use it while wielded on mechs to break the occupants out. This
takes 5 seconds (or 3 in an unenclosed mech like a ripley)
When you die in a mech you no longer automatically get ejected.
refactors fire axe cabinets to support more items than the fireaxe
makes some vehicle code better
closes #70845 (you can still enter a mech without limbs, i think thats
fine because you can use it to protect yourself from death in a
dangerous situation or something until someone breaks you out with the
really large crowbar)

## Why It's Good For The Game

<!-- Argue for the merits of your changes and how they benefit the game,
especially if they are controversial and/or far reaching. If you can't
actually explain WHY what you are doing will improve the game, then it
probably isn't good for the game in the first place. -->
robotics having a giant ass crowbar to break people out of mechs seems
like a fun idea
you currently cant exit a mech if youre incapacitated inside it unless
you DIE

## Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
mark your PRs to prevent unnecessary GBP loss. You can read up on GBP
and it's effects on PRs in the tgstation guides for contributors. Please
note that maintainers freely reserve the right to remove and add tags
should they deem it appropriate. You can attempt to finagle the system
all you want, but it's best to shoot for clear communication right off
the bat. -->

🆑 Fikou, sprites by Halcyon
refactor: fire axe cabinets support items that aren't fire axes
balance: mechs no longer eject you when you die in them
add: Adds a giant crowbar to robotics, it can break open mechs to eject
their pilots.
/🆑

<!-- Both 🆑's are required for the changelog to work! You can put
your name to the right of the first 🆑 if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
